Tim Guinee, who as of late has recurred on The Good Wife, has booked a role on Showtime’s Homeland, TVLine has confirmed.

Details on Guinee’s character, as well as his episode count, thus far are filed as “top secret,” though we’ll remind you that the show was looking to cast Brody’s chief of staff, so perhaps they don’t want to broadcast that the war vet’s run for Congress is a success.

Homeland Season 2 premieres Sept. 30. Guinee also can be seen this fall on the NBC’s new post-apocalyptic drama Revolution, from J.J. Abrams and Eric Kripke.
